Syphon Elbows

 

The Filton® Syphon Elbow is a useful accessory with for the rotary P.B., R.E.B., C.B. and C.B.N. unions (type S.T.) whenever there is a steam service. The majority of steam cylinders are fitted with a curved syphon tube for condensate extraction. If the diameter to length ratio of the cylinder end bore prevents the use of a curved syphon tube from being fitted, the syphon elbow should be used (see illustrations below). The elbow allows two pieces of straight pipe to be joined and the hinge opens to allow for fitting through the bore of the cylinder end. It is advisable to fit the syphon tube to port ‘O’ of the rotary union type S.T., locking it with a backnut and checking the down pipe position in relation to port ‘B’ before installation.

 

The syphon tube assembly is cantilevered from port ‘O’ in the rotary union. In certain applications, the syphon tube length and weight can cause too much deflection and load on the rotary union bearings; it is therefore sometimes necessary to include a syphon tube support bearing within the cylinder.

 

The standard materials used for syphon elbow construction include brass for the body, stainless steel for the hinge and fluorocarbon for the sealing ring. For heavy syphon tubes and corrosive conditions, the bodies may also be provided in stainless steel (add the code ‘S’ to part number). To select a suitable syphon elbow, check the centre tube thread (dimension ‘O’ of the rotary union) and match it to thread ‘A.’

Note: (i) 'G' pipe threads are to BS.2779 and ISO 228/1 (formerly B.S.P. parallel).

 

If flanged fittings are required, one flange should be a swivel type to aid stress-free fitting. A swivel flange should always be used if the opposite end is a fixed threaded type. Flanges are available to the following specifications: A.F.N.O.R., A.N.S.I., BS.10, BS.1560, BS.4504, D.I.N. and I.S.O.
